EFI Honda 90 help!

I wonder if Honda marine dealers make it a routine to check the Honda EFI 90's that might suffer from this leaking plastic t/stat cover by actually make it part of the inspection process during routine service and have the new metal covers in stock to put on the engines that see salt water use before they even start leaking as a preemptive meaure?This would just would seem like a common sense move. In our business we use serial numbers to identify possible problems and remove the stock and make corrections existing stock before it gets to the customers. We send our own tech updates to our own customer base to advise them of possible issues with products we have sold so they are not blind sided. They are worded in a way that does not cause mass hysteria.

The first of September I had some friends on the boat all day, and far from home. The next morning I went down to do some clean up and polishing then planned a quick ride at sunset. Well when I went to start the engine all I got was the engine turning but no start. I have never had a problem starting the 2007 Honda 90, so this was a little un-nerving. I'm lucky this happened at my slip and not in NY Harbor.
The problems were #1, a corroded 10 amp fuse on the engine (The bottom fuse). I noticed when I was trying to pull the fuse it seemed stuck. when it finally came out, one of the prongs just fell off into the water. It had corroded off leaving a good amount of gunk stuck in the fuse block, it was also blown. At first I thought the problem was just a rare, not very explainable occurrence. As clean and polished the engine looks I never expected what I found next.
After I pulled all the fuses and replaced the bad one (I put dielectric grease on the fuse connections) the engine started up first time. I think that fuse controls the fuel pump. Well I stood there admiring what a good job I did and how lucky I was to be doing that job at my slip and not in any shipping lane when I noticed problem #2,a small drip at the bottom of the engine near the bottom spark plug. It took about a second to recall the subject of this thread and find the leaking T-stat cover that was mentioned. If I hadn't read your experience with this problem it may have turned into an even bigger deal down the road...or channel.
I'm getting the part from Boats.net, when I asked on the phone they told me the part # on their site was the Aluminum cover , but they see a different # on their screen and sent me the wrong part, no problem the correct part (11-19315-ZY9-000) is on the way no problem.
If I was paying more attention in July when I read your experience I would have gone out , checked, removed and replaced that part .
If you have this engine make sure you have spare fuses on hand and do some preventative maintenance, spend the few dollars and change that cover.

Mike,

Thanks for the heads up. I went ahead and ordered and received the new
aluminum thermostat cover and also got a spare thermostat just in case.
I'll make sure I've got spare fuses also. Lake Powell is no place to be
stranded (or anywhere for that matter)

Thanks,
Mike
